  Working Principles
Click to ViewMany substances absorb light. However some of them, after absorbing light of a particular wavelength and energy, emit light of a longer wavelength and lesser energy. Application of this phenomenon is the basis of fluorescence microscope. In practice, microbes are stained with a fluorescent dye and then illuminated with blue light. The dye absorbs blue light (shorter wavelength) and emits green light (longer wavelength). In a fluorescence microscope, a high intensity mercury arc lamp is used as the light source. It emits white light, which is passed through an ‘exciter filter’. It allows only the blue component of the white light (the white light consists of seven colors, which in the decreasing order of wavelength are violet, indigo, blue, green, yellow, orange and red) to pass through it and blocks out all other color components. The specimen is either previously stained with a fluorescent dye, such as acridine orange NO, acridine yellow or may have fluorescent protein expression system. Thus, the eye perceives the stained portions of the specimen as glowing green object against a jet-black background, whereas the unstained portions of the specimen remain invisible.

  User Instructions
All microbial and plant samples can be observed under light microscope. Fluorescent protein expressing and stained samples that are compatible with I3, N2.1, GFP and A filters can be documented. Sample preparation/tissue sectioning should be carried out by the user on their own.
